Party adaptation and change and the crisis of democracy

This article is the introduction to a special issue of articles written in honour of Peter Mair. The general theme of the issue is party adaptation and change, which is traced here through an analysis of contributions by Peter Mair as an individual author or with co-authors. The result is an assessment of the current state of the art of what can be cumulatively considered Peter Mair's theory of party adaptation and of the debate it has generated up to and including the contributions included in the special issue itself.
